Summary:A method for recognizing a usability of a control device of a safety device in a vehicle includes: applying a voltage to the control device; acquiring a voltage curve or a current curve at the control device; and recognizing a usability of the control device as a function of the acquired voltage curve or of the acquired current curve. In particular, the correct polarity of an inductive actuator having a freewheeling diode is recognized, because in the case of incorrect polarity the inductive actuator is bridged by the freewheeling diode.
